numeric_limits::min_exponent10

Returns the maximum negative integral exponent that the floating-point type can represent as a finite value when a base of ten is raised to that power.

static const int min_exponent10 = 0;

Return Value

The minimum integral base 10 exponent representable by the type.

Remarks

The member function is meaningful only for floating-point types. The min_exponent10 is the value FLT_MIN_10_EXP for type float.

Example

// numeric_limits_min_exponent10.cpp
// compile with: /EHsc
#include <iostream>
#include <limits>

using namespace std;

int main( )
{
   cout << "The minimum base 10 exponent for type float is:  "
        << numeric_limits<float>::min_exponent10
        << endl;
   cout << "The minimum base 10 exponent for type double is:  "
        << numeric_limits<double>::min_exponent10
        << endl;
   cout << "The minimum base 10 exponent for type long double is:  "
        << numeric_limits<long double>::min_exponent10
        << endl;
}

Output

The minimum base 10 exponent for type float is:  -37
The minimum base 10 exponent for type double is:  -307
The minimum base 10 exponent for type long double is:  -307
